Abstract

A system and method for managing a plurality of snapshots as provided. A set of metadata describing a file system is contained within the file system so that a snapshot of the file system includes the associated metadata. Backup client file systems are restored to a backup server using conventional dump and restore techniques. The backup server then utilizes a user-defined snapshot management schedule to manage the set of backups associated with the backup server. Such management of snapshots can include deletion of snapshots based upon a variety of parameters including the time stamp.
